although it is to be understoodthat the paper as such may be used lior other pur` poses.

The objects ot my invention are to provide a process by which a number of com paratively narrow long strips with thinned edges may be simultaneously formed and cut from a single strip `ofwide materiaL,`

which method `will be capable of being carried out by a suitably designed apparatus, and to provideone iorm of apparatus which is capable ot carrying outsucha process with accuracy and speed. :Other objects will appear in the description which follows.`

lReference will now be made to the appended drawing ,in which.:l i

The figures arelargely schematic and are not intended to show all kthe v'details of the iinished machine, as thesewwould obscure the features and combinations of parts in which the invention resides. i. There is.

,ports 23. i

Upon the' several shafts 16 there are shown, however, a completely operative mechanism, amply suiiicient to enable any skilled designer toconstruct a machine. n

. Asuitably shaped framel supports the various Operative parts of the ymachine.v

This is extended at the top to form what is vterrified a turtle-back 2, comprising side 'flanges 3, of which one only is shown, between which extend idle rollers 4 indicated ,insection These flanges act as guides to direct the paperto the mechanism hereafter to be described. A roll of lmaterial 5, which will usuallybe paper, is rotatably `supported on the shaft 6 supportedin suitable bearings 7, carried by a bracket 8 on the frame. The paper 7 is drawn from this roll over an idle roll 8 and then over the rolls 4, and thence is passed to more closely arranged snubbing rolls 9, where the paper is drawn in a series of sharp turns,as shown, in the drawing, these snubbing rolls 9 being supported between thesides 3. Beneath thelast snubbing roll 9 there are arranged aseries of abrading wheels 10, each'of which isvmounted on `the frame 1 by means permitting of its'adjustment. As shown, there is provided 'for each abrading wheel 10 a `fixed block 11 with a guilde 12 which dovetails into a correspond ing guideway' in the ytransversely slidable member 13. Upon the member 13 there is mounted asupport 14 adapted to slide in a direction at right angles to the irst mentioned move-ment. This block 14 supports, by means of brackets 15, the abrading wheel l10on an axis 16. The second described mo tion is controlled by the hand screw 17 passing through the down turned end 18 of the slide 13 and bearing against the end of slide 14. The parts can bev locked in adjusted positionby a bolt 19. i V

" I prefer to mount these abradingwheels in a -staggeredrelatiom as shown in Fig. 3, mounting 011e series froml downwardly eX- tending supports, and the other series from similar upwardly extending supports, as this permits closer `positioning of the abrading wheels. Opposite each ot the abrading `wheels is an anvil pulley 20 supported on shaft 21 carried between brackets 22 of a support 23 adjustable, by means ofthe bolt 24, on' rod 25 common to all vof the supmounted driving pulleys 26, :from `which there are'run driving belts 27 to correspondllO ing driving pulleys 28 mounted on a shaft 29, this shaft being driven by suitableshafts and gearing 30 driven by motor 31. The abrading wheels l and their corresponding anvils 2O are so shaped as to form grooves in the paper passing between them in the form shown in Figs. 3 and 4. These abrading wheels are of greatest diameter at the central part of their periphery, as indicated at 32, and slope gradually to the edges, so that the grooves formed inthe paper will be of the form indicated in Fig. 5. The anvil pulley used in this form has a straight cylindrical surface, las indicated in Fig. 4.

As shown in Fig. 5, the paper has formed therein at spaced intervals grooves 33 with sides inclining evenly, so as to give a shallow V shaped cross section. 4The dimensions shown in Fig. 5 are much exaggerated, since in practice the grooves would be normally spaced apart by a distance of several inches and the depth of the groove in comparisonk with its width would be very slight. For

instance, in paper .004 thick, the groove roll would tend to bend the paper up toward the abrading wheel, which would thus wear off the upper surface. In Fig. 7 the -abrading wheel has Ia rounded surface 36, while theanvil wheel 37 has a plain periphery as before.

`After passing the `grooving means, the paper strip 7 passes yaround the idle rolls 39 'and 40 and between a series of staggered slitting disks 44, thence over another idle roll to the driving rolls 46 and 47. These driving rolls are driven by lsuitably interacting gears k48 and 49 upon their shafts 50 and 5l, shaft 50 being driven by gear l525 from gear which is driven from the motor 3l. The gear 53 also drives gear 54 which actuatesfthe cutting disks by suitable mechanism. These cutting disks are carefully arranged in alignment with the several abrading wheels, so that they will slit `the paper longitudinally and medially of the grooves formed therein, the paper beingguided between the sidewalls 55, kone only of which is shown. After leaving the roll 46, the paper, now in the formof comparatively narrow strips, passes over idle rolls `56 and 57, to the take-.up rolls 58 and 59 driven by the belt 60 from a pulley 61 driven by motor `31. k'This belt drive lconstitutes 4a frictiontakeaip, so as to maintain the paper under tension during winding and permitting slip. The kdriving rolls 46 and 47 maintain the paper under tension back through the machine to the snubbmg rolls l9 which, by reason of the sharp turn given to the paper, vact vas -a -suflicient resistance to the pull to maintain the proper tension.

ln Fig.` 2 a strip of paper 7 is shown, the upper part of which is indicated at 62 as uncut, and a series of grooves are formed in it, as indicated at 63, some beginning ahead of the others, because of the positions of the alternate abrading wheels. The cuts 64 are indicated in full lines in the center of these grooves. The continued dotted lines indicate the thin portion of the paper on each side of the central cut, so that at the lower end of this figure there is shown -a series of strips having thinned edges. rPhe outer edges of the outer strips are not thinned. e

It is obvious that the process herein described can be carried out in a wide variety of ways,particularly as relates to the formation of l`a strip of paper with grooves ltherein, and that machines diering widely in structure and mode yof operation fromthat herein shown maybe employed. I contemplate v'as within the scope of my invention, all such alternate and modified processes vand all such modifications and mechanical equivalents that can beutilized in machines of the characterdescribed, as fall 'within the terms of the following claims.
